Health workers backed a motion of no confidence in their bosses at a meeting at Whipps Cross Hospital on Thursday of last week.
The meeting brought together the RCN, Unison and Unite unions. Only one person voted against the motion. Workers also voted to back industrial action to defend jobs and wages, with two abstentions.
Unison is preparing to hold an indicative ballot for strikes this week.
Management has targeted Charlotte Monro, longstanding Unison branch chair and health activist. She has been charged with multiple counts of gross misconduct.
Around 200 workers protested on Monday of this week at Whipps Cross main gate. A demonstration has also been called for Saturday of this week.
Hundreds of workers face “downbanding” wage cuts. Those who agree to be moved to lower grades will keep their current pay for 18 months.
This is down from the three years agreed in the national NHS conditions.
Bosses have threatened that anyone not agreeing will get their pay cut after only a year.
