My job is very stressful. 2 people from a sub team keep trying to palm their work off onto me. My supervisor has said I'm not to do their work. This sub team keep pulling this stunt everytime my supervisor goes on annual leave by sending emails. My workload is too much as it is. I feel like crying because I feel the overall manager is going to side with the sub team. The sub team are lazy and always walk round the office chatting about non work and using their phones. I feel like deleting the main instigator off Facebook as she has no respect for me. I wish I had not accepted colleagues on Facebook. No-one gets this and they think I am a soft touch.
