Colleague at work is leaving in 2 weeks. Collection has been started by another colleague who has now been signed off sick for 2 weeks. I've been asked by email to take over the collection. Tbh I've done my fair share in the past and I find them a pain. As we don't really work together as a team it's hard to get money off anyone and even if you send a team email out with your bank details it largely goes ignored so you either end up with a few quid or have to spend time chasing people, time which I don't have. Then you have to go and buy the present! I don't even know the person very well. WIBU to politely refuse?
