Lots of people have great experiences volunteering, but be aware its not always sunny.
If it does not fit you or you encounter problems, it is often down to institutional / management / culture problems within the charity itself. The weight of blame is sometimes passed to the volunteers. Never get so involved you feel unable to walk away.
Be aware many charities get too many volunteers and this can lead to the charity being overwhelmed, so they do no individual 'thanks but no thanks' contact so your application is seemingly ignored, which in itself is poor public relations.
Volunteers who are taken on can be seen as very expendable due to easy replacement in some sectors. Some charities expect volunteers to behave as if they are employees, with the same obligations of a paid contract. Application forms can be very long and intrusive. Some I have looked at make paid employment applications seem short and casual by comparison. Some I have binned due to excessive intrusiveness. One which was just for casual 'gallery sitting' now and again (no high value displays) who wanted my entire employment history from school 20+ years back, which was absurd.
Where possible, speak to volunteers who have already worked for some time at whatever you hope to volunteer for and do it away from the volunteering centre. I have several friends who were very unhappy and found it hard to leave due to a sense of obligation. Psychologically it can become a 'replacement employment', where turning up to give your unpaid time out of kindness turns into a false obligation as if still paid, under contract obligations and needing money for mortgages etc.
Some years back I had looked into volunteering for the NT as they had a massive recruitment stand about it in the main entry lobby, ask at reception it said. When asking at the reception the staff claimed they had no knowledge of any recruitment drive and had no forms/info they could give out. Things like this are major clues to poor management and communication.
The NT has ongoing problems with attitude towards volunteers (do a web search). I know someone who used to run and edit an NT regional publication, as a volunteer. When they left their post was not advertised for other volunteers to apply for, but instead they passed the role directly to their close friend, who had never previously volunteered in any capacity for NT. I was pretty disgusted the NT thought this exclusionary behaviour acceptable. Its another clue as to how volunteers are seen by the charity. As with people when they show you who they really are, recognise a charities attitudes to volunteers the first time they show you.
Another friend worked in a hospice shop chain for many years as a volunteer. He was then diagnosed with MS and soon found it hard to walk the mile to the shop. Despite his being on disability benefit (he was that ill) they refused to help with his local bus fare, despite that being a legal use of charity money (they can pay volunteers expenses, a lot of charities don't like to admit that). Then when he had to go to medical appointments he would be criticised for not 'booking them' far enough in advance, even though he told them when he knew himself. He needed a break to visit far off family and was told he could not inform them he would be unavailable for volunteering for 2 weeks of the next month, he had to officially 'request leave'. When he had to reduce his volunteering hours it was made clear he was letting them down. Staff were also frequently moved between the many shops of the chain, mostly to break up and respond to accusations of bullying.
A friend of a friend worked for Oxfam as a volunteer. He eventually walked out after being verbally attacked by the shop manager for not processing books fast enough, despite his giving time for nothing. He had started volunteering there after a mental breakdown.
Legal and Health and Safety issues can also be problems with charities. I volunteered for a county Wildlife charity (not Gloucestershire). I eventually walked away after:
- The employed staff in charge had no idea of where any fire extinguishers were, despite catering food for the public over open wood fires with literally foot high flames on fires at waist height. When I mentions burns risks and where was the fire extinguisher etc "I think there is one down in the shed, maybe behind the door". My asking how long they thought they had if someone caught on fire was not looked on kindly.
- They were selling alcohol to the public illegally at multiple events (no temp licences "Its not worth us bothering to do that.")
- Male volunteers in their 30's were given privileges by the management (who were also male 30's), so it became a private 'club'.
- Volunteers being treated dismissively (events cancelled days in advance but no volunteers informed, so still turned up having taken leave from work, swapped shift especially etc)
- Both local staff and head office being too rude to even acknowledge hours of commissioned work from volunteers when the project was turned in to them.
I also know someone who loves her charity work and experiences from volunteering, there are great ones out there. If that turns out to not be you, don't assume you are at fault and don't hang around hoping it will improve, just move to a different charity asap. Life is too short. Its not a job, its a kind donation of your valuable personal time for free, when you could be doing other things. It should be respected by the charity receiving it.
