First of all do your maintenance members provide they're own tools? second do you offer any tool allowance and if so how much do you offer.
I recently worked for an apartment complex. We had a small staff and actually asked that they do not bring their own tools into work.
The good thing was that the staff did not have to worry about damaging their tools nor did they have to worry about losing them. The bad part was that the owner would only buy the inexpensive (re: Harbor Freight) tools so the staff would still bring their own in if it was something they used regularly.
When I worked for a newspaper company, we also provided the tools - but only the smaller ones. If there was something major that was needed, usually one of the staff had the tool at home. They would bring it in to use - and it opened up the problems with the tool breaking on the job (usually the cordless drills). We tried to discourage the practice, if we could.
Can I say it was the best option? Not sure, it worked because I did not have to hear that they did not have a specific tool. We were able to keep projects fluid by having company tools. The bad part was that the smaller tools "disappeared". Of course, the cheaper tools never left just because no one wanted them.
I worked for an apartment complex and then an HVAC-R company and they both had the same style of basic hand tools were provided by employees but the more expensive equipment was provided by the company, but we did have the flexibility with the HVAC-R company to pick up a tool at the supply house if something broke or we were missing something and on our way to a job, however as you can imagine that got abused quite a bit, people did some major upgrading with that i.e. bringing in harbor freight linesman's and replacing them with the best Klein's money could buy when they broke, now i have a gov. job and they provide everything though i still use some personal tools out of preference or for things like duct work that i have no need of these tools at home and there is no sense in having my employer buying them, i will say on a semi unrelated note it is nice not having to lug my tools back and forth
