As has rightly been stated by many, this is only a rumour network - the truth will appear later. In the mean time it is important that we all keep our powder dry and wait to see what actually appears. Like many of us have been saying, this is the moment to join BALPA and have your say. If you do not like what is being offered (and if what is being written here is true then none of us will!), you can vote against it.
The choice to join BALPA is a personal one. If, however, you do not join, please do not so much as raise a whimper anytime, anywhere to anyone about any aspect of your terms and conditions - the only person to blame will be yourself!
