Sefton Central Labour MP Bill Esterson called a consulting company's recommendation to dramatically alter Sefton workers' pay and conditions ludicrous.
Bill said Fresh Care Consultants' recommendations which include cutting Sefton New Directions pay by up to 26% were insulting.
The MP said: "The recommendations which I have seen are nothing short of ludicrous.
"As well as cutting staff pay by up to 26%, these consultants are also suggesting that there's less holiday entitlement, sick pay is slashed, weekend and evening pay is reduced and 53 staff are made redundant.
"Many of the Sefton New Directions workforce are already extremely low paid. By slashing pay by up to 26%, many of these workers will be sent below the minimum wage.
"Instead of getting to the core of the problem to work to make Sefton New Directions a strong and viable business, these consultants are suggesting the easy option of taking out the company's failing on the already low paid workforce.
"Many people who rely on Sefton New Directions services have contacted me to voice their concerns about these proposals. They can see that cutting staff to this level and cutting wages and pay and conditions to this extent will lead to a reduction in quality of service. They are justifiably concerned.
"Any changes must protect the most vulnerable that includes elderly and disabled people who rely on SND for day care and homecare and it includes staff on low pay with no job security and with families depending on them.
"Sefton New Directions must be made a viable standalone business in its own right, but these recommendations don't appear to putting the company on a strong footing, but will instead weaken it.
"And yet again, what we are seeing is another attack on the low paid right here in Sefton."
